Ferns coach Tony Readings said he has a good relationship with the Chinese coach but didn't agree with his actions.
"I have always got on very well with the Chinese coach, very well. He's a very good coach," Readings said during his postgame press conference.

"I would never go out of my way to do that to an opposition player. You've just got to let the players on the pitch do their business and the last thing we want is to influence things. We should always be backstage, not on stage. And I'm sure we'll meet again because we always play China a lot. We'll get on well again and there will be no problems at all."
